I purchased this item six months ago. I had the same model before. I am selling this one because I bought a different hair dryer this time. Thank you. This hair dryer uses a "double flow twin negative ion" system that generates negative ions from both the inside and outside. It has a high power of 1300W and a large airflow of 2.0m3/min. You can use it while it's standing, without holding it, which is convenient for long hair drying sessions. The airflow can be adjusted steplessly from minimum to maximum. It uses a "flex nozzle," and you can change the air pressure and spread by rotating the outer nozzle. Power supply/Voltage: AC100V 50/60Hz compatible Cord length: 1.7 m Power consumption: 1300W Size/Weight: When in use: Approximately 203(W) x 212(H) x 85(D)mm (with concentrator)/ When folded: Approximately 203(W) x 131(H) x 85(D)mm No claims and no returns to prevent swapping.
